# In-Sight ViDi System Requirements

The topics in this section cover the requirements for the In-Sight ViDi adapter used to develop your vision application, along with requirements to connect to an In-Sight D900 series vision system.

CAUTION: The In-Sight Vision Suite and In-Sight ViDi software require that a valid Cognex Security Dongle be installed directly to PCs running the software during all phases of operation (programming, processing, training, testing, etc.). Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.
